bug#57292: [PATCH] services: gdm: Add packages for accessibility settings.

[Dariqq]

gdm needs the "/share" subdirectory of these packages present in XDG_DATA_DIRS
such that the accessibility settings work:
- gnome-control-center: For the icon.
- dconf: To be able to change settings.
- at-spi2-core: contains accessibiltiy dbus-service.

* gnu/services/xorg.scm (<gdm-configuration>)[gnome-shell-assets]: Add
at-spi2-core, dconf, gnome-control-center.
